KPRC reported that Williams was involved in thousands of "short calls" or 911 calls lasting no more than 20 seconds between October 2015 and March 2016.

Police said Williams was questioned about the short calls and said, "she often hangs up on calls that have not been connected because she did not want to talk to anyone at that time."

On March 12, KPRC reported, Williams hung up on a caller reporting a robbery that resulted in the death of a convenience store manager. The caller, engineer Hua Li, told the station that he was disconnected before finishing his first sentence.

Li called 911 again, reaching a different operator who allowed him to complete the call.

The following day, Williams took a call from a security guard reporting two motorists street racing on Interstate 45. Before the caller could give his location, Williams disconnected the call. Police said she was recorded saying, "Ain’t nobody got time for this. For real."
